1, utilize solar opto-electronic board to produce the DC15V working power
Directly adopt commercially available solar opto-electronic board, the voltage lead-out wire is linked into binding post J6 shown in Figure 2, after the counnter attack charge protector, produces the working power SUN_Vm of DC15V.
2, the AC220V civil power is converted to the DC15V working power
Working power reaches the mutual components and parts annexation of switching as shown in Figure 3: the binding post J1 of alternating current 220V power supply, export from pin OUT2, the OUT3 output of transformer T1 after process fuse F1, first resistance R 1, the second resistance R D1 link to each other with two voltage input ends of pin IN1, IN2 of transformer T1.The 4th capacitor C 44, the 5th capacitor C 45 strobe in the alternating current 220V circuit.Transformer T1 is the transformer of specified output+15V.Transformer T1 is connected with three terminal regulator W1 with rectifier bridge BR1, first capacitor C 1, the 3rd capacitor C 13, three terminal regulator is 78M15, BR1 is a rectifier circuit, and the 3rd capacitor C 13 is for there being polar capacitor, and first capacitor C 1, the 3rd capacitor C 13 and three terminal regulator W1 play the effect of voltage stabilizing rectification.

3, power supply switches mutually
Working power 15V_SD output connects power supply switch circuit, and power supply switch circuit comprises two parts: 1, the switching of civil power working power and solar energy working power, working power are simultaneously to standby working power charging; 2, the switching of operate as normal power supply and standby working power.
1, the switching of civil power working power and solar energy working power
The circuit diagram components and parts annexation that voltage switches is as shown in Figure 4: the current voltage+BATT of stand-by power supply, voltage comparator U10 are LM358.Over-charge protective electromagnetic relay S1, cross that to put protection electromagnetic relay S2, the 3rd electromagnetic relay S3 be rated voltage 15V direct current electromagnetic relay, play over-charge protective control respectively, cross and put the purpose that protection control, civil power working power and solar energy working power are switched.
Wherein relatively be+8V to be connected to the reference voltage 4.0V that voltage comparator pin IN1-provides comparison among Fig. 4 by the 6th resistance R 53, the 7th resistance R 54 with reference voltage.The pin IN1+ that the solar energy working power is connected to voltage comparator U10 by the 8th resistance R 55 and the 9th resistance R 56 provides 4.0V that systematic comparison voltage and IN1-provide relatively, control terminal OUNT1 by voltage comparator U10 exports solar energy working signal SUN_220AC then, after the amplification of this signal by resistance the tenth resistance R 77, amplification the tenth triode Q10, drive the 15V direct current electromagnetic relay, to reach the purpose that civil power working power and solar energy working power are switched.
Fig. 5 wherein+the 8V signal of telecommunication is connected to the second voltage comparator U7 by the 11 resistance R 48, the 3rd diode D28, second voltage comparator is the LM358 chip, the pin IN1-of second voltage comparator and IN2-are to provide the reference voltage 6.2V of comparison.Provide current voltage and reserve battery power supply+BATT is connected to the second voltage comparator U7 pin IN2+ by the 12 resistance R the 44, the 13 resistance R 45, relatively play preventing the protection of putting with reference voltage.Reserve battery power supply+BATT is connected to the second voltage comparator U7 pin IN1+ by the 14 resistance R the 46, the 15 resistance R 47 current voltage is provided; relatively play with reference voltage and to prevent the protection that overcharges; by the control terminal OUNT1 output over-charge protective signal GCBH of the second voltage comparator LM358 chip, OUNT2 exported puts guard signal GFBH then.By the difference coupling of resistance value, can adjust the value of two comparative voltages easily.
Its switch operating principle is: the switching of power supply realizes by the comparator control relay, in Fig. 4 circuit diagram, front end at comparator, we have selected the reference voltage of 4.0V as circuit comparator, resistors match situation according to this circuit diagram, when sun-generated electric power SUN_Vm by the 9th resistance R 56 minutes voltage when reaching the 4.0V reference voltage, that is the voltage of SUN_Vm reaches the condition of work of working power when reaching 12.0V.The comparator upset, control terminal OUNT1 output solar energy working signal SUN_220AC by voltage comparator U10, this signal is by amplification the 3rd electromagnetic relay S3 action later on of resistance the tenth resistance R 77, amplification the tenth triode Q10 among Fig. 6, the working power 15V_Vm of sun-generated electric power Sun_Vm and alarm is connected, and sun-generated electric power is served as working power.
On the contrary, the voltage that detects voltage when solar energy is lower than 12.0V, illustrates that sun-generated electric power does not reach the condition of working power, the 3rd electromagnetic relay S3 of Fig. 5 discharges, the solar-electricity resource loop is disconnected, connect the mains supply loop simultaneously, mains supply serves as working power.The tenth triode is the core electric elements of BC847 as amplifying circuit, is the effect that IN4007 has played step-down, rectification for preventing the too high damage that system is caused of solar voltage, increasing by the 20 diode D23 specially.
No matter be that sun-generated electric power or mains supply are when serving as working power, all charge to stand-by power supply simultaneously, as shown in Figure 5, when the current voltage of reserve battery power supply+BATT through resistance R 47 minutes voltage when reaching the 6.2V reference voltage, that is the voltage of reserve battery power supply+BATT reaches the limit that overcharges when reaching 14.5V.The comparator upset; control terminal OUNT1 output over-charge protective signal GCBH by second voltage comparator; ten six resistance R 69, ten seven resistance R 72, ten eight resistance R 74 of this signal by Fig. 5, form the amplification of first amplifying circuit by the 6th triode Q6, the 7th triode Q7 after, charge circuit is cut off in over-charge protective electromagnetic relay S1 action.So under the normal condition, the voltage of stand-by power supply is always low slightly than operate as normal power source voltage.
2, the switching of operate as normal power supply and standby working power
The circuit diagram components and parts annexation of stand-by power supply work is as shown in Figure 6: because when the working power of system can operate as normal, the voltage of stand-by power supply was always low slightly than operate as normal power source voltage, so stand-by power supply can not provide operating voltage.When normal two-way working power all can not the back-up system operate as normal, stand-by power supply will be realized seamless link, enables the work of stand-by power supply back-up system automatically.
When stand-by power supply served as working power, battery just discharged, and along with the prolongation of operating time, voltage will reduce.In order to prevent that rechargeable battery from excessively discharging electric charge; be provided with especially and put defencive function; as shown in Figure 4; when the current voltage of reserve battery power supply+BATT through the 13 resistance R 45 minutes voltage during less than the 6.2V reference voltage; that is the voltage of reserve battery power supply+BATT reached the limit of putting during less than 11.5V.The comparator upset; control terminal OUNT2 by second voltage comparator exported puts guard signal GFBH; this signal is formed by the 19 resistance R the 70, the 20 resistance R the 71, the 21 resistance R the 73, the 22 resistance R 75, by amplifying triode Q8, Q9 after the amplification of second amplifying circuit, crosses to put and protects electromagnetic relay S2 action that discharge loop is cut off.
So when backup power source voltage was lower than 11.5V, undervoltage alarm information was sent out from the trend user by system.When standby voltage is lower than 9V, system disconnects and being connected of peripheral warning device.The work of back-up system central processing unit.No matter be power supply of alternating current 220V power supply or stand-by power supply power supply, system preferentially detects solar energy to detect voltage, as long as the voltage of system's sun-generated electric power is higher than 12.0V, system switches to the operate as normal of sun-generated electric power back-up system with regard to the very first time.
